Composition and some properties of human erythrocyte acetylcholinesterase prepared for use in medical practice were studied. After electrophoresis 5 protein bands, two of which exhibited the enzymatic activity, were detected in the preparation. Three isoenzyme forms of acetylcholinesterase, dissimilar in their electrophoretic mobility, were detected in the preparation by ion exchange chromatography on DEAE Sephadex A-50. The preparation did not contain hemoglobin, thromboplastic substances and group isoagglutinogens A and B.
